I've heard reports of this type of thing happening with the AVR, and
not limited to any particular AVR part.  I suspect they may be caused
by brown-out which can result in unpredictable behavior.  I suspect
that during programming, some type of power supply glitch occured, but
I don't know of any way to tell for sure.  I did ask my Atmel field
rep about reports of this problem, and he basically alluded to the
same conclusion - a power supply problem during programming might be
the cause, but he had nothing definitive.  He was not aware of any
errata or anything else that could cause fuses to be unpredictably
modified.
